exposed the pupa to sharp frost, placing them in a shallow tin on 

 a grass lawn, and then returned them to the warm room. Later 

 in the month he repeated this treatment, but only three of the 

 pupaB appeared to be killed by the process, nor did the time of 

 emergence appear to be affected by it, as the imagines came forth 

 at the same time as others kept under normal conditions, and their 

 colour and markings also appeared to be unaffected. 



Mr. F. W. Frohawk said that after many years careful study of 

 the species he was strongly of the opinion that C, ediim may occa- 

 sionally survive the winter in the most sheltered spots in Devon 

 and Cornwall, provided there is no frost or continued damp and 

 cold, as either are fatal to the larvre. He had no doubt that, given 

 fine weather, C. ediim deposits ova very freely directly after 

 reaching our shores in the spring, the normal time being, for their 

 first appearance, the end of May or early in June; these under 

 favourable conditions produce imagines in August, and a succession 

 of broods is the result. 



APRIL 9th, 1914. 

 Mr. R. Adkin, F.E.S., in the Chair. 



Mr. R. Adkin exhibited three specimens of iJaxychiia fascelina, in 

 one of which the usual black transverse lines were to a great extent 

 replaced by yellow, and in another the usual yellow freckling was 

 absent and the black markings somewhat intensified. Both these 

 specimens are figured in Barrett's "Lepidoptera of the British 

 Isles." The third specimen was similar to the second, but the 

 black markings, were less strongly produced. 



Mr. Stanley Edwards exhibited a number of conspicuously marked 

 Heterocera from Burmah, including Ariiina onjns, a very beautiful 

 lithosiid, Kiichroitiia foiiiwsa, a very strikingly marked species of a 

 group allied to what we commonlj' call zygsnids, Heterusia 

 (Devanica) edoda, a species of Chalcosiidae, one of the most brilliantly 

 marked of the exotic families of moths, CrisJma {Petida) niacropfi, a 

 huge species of the Noctuidse remarkable for the extreme develop- 

 ment of tibial tufts, and Abraxaphantcs peravijita, a large geometer 

 allied to the British Abraxas sylvata (vlmata). 



Mr. Alfred Sich exhibited specimens of Lita lencumelanella, 

 Zeller, from near "Weymouth, first described by Zeller in 1839, and 

 taken in England by Boyd in 1858, who found the larva in the
